设置NodeManager启动UCM

装了UCM 11g的虚机，回到公司用Console怎么也起不起来，一直报 的错，尝试在EM用NodeManager去启动，更加惨，除了原来的错外，还报了一大堆类似
java.lang.ClassNotFoundException: oracle.jrf.wls.JRFStartup
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:247)
at weblogic.management.deploy.classdeployment.ClassDeploymentManager.invokeClass(ClassDeploymentManager.java:253)
at weblogic.management.deploy.classdeployment.ClassDeploymentManager.access$000(ClassDeploymentManager.java:54)
at weblogic.management.deploy.classdeployment.ClassDeploymentManager$1.run(ClassDeploymentManager.java:205)
Truncated. see log file for complete stacktrace的错误。查了下，发现是要调整nodemanager.properties的设置，使用以下步骤：
Stop All Managed Servers
Stop Node Manager
Update nodemanager.properties
set
StartScriptEnabled=true

Restart Node Manager
Restart managed Servers from WLS Console.
然后重启EM，启动UCM Server实例，竞然神奇的好了，搞不明白是啥原因。
